Re: [DISCUSSION] Specify tasks to skip when triggering DAG

[Giorgio Zoppi]

Hey Jurek,
Just a question about  the future development, is the XComm backend
replaceable now? The real power of Airflow is the 'defacto' the glue
between different ways of mangling data, such as Python is the glue when
you need to implement things a lower level, ie. Altair Simulation software
is written for critical parts in C++ and binded at upper level in Python.
Same we can state for Tensorflow, numpy. About my question: it would be
nice to have as XComm backend a queue like redis or a non structured
database for allowing scaling but i am not sure
it it makes sense since XComm is just for short messages.
Best Regards,
Giorgio
